Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lift elevator, and more particularly to an improvement in a car frame thereof.
[0002]
[Prior art]
FIG. 18 schematically shows a general structure of an elevator. In a normal elevator, a car 1 for passengers is connected to a counterweight 2 by a rope 3, and the rope 3 is operated by a hoisting machine 4 to raise and lower the car 1 while being balanced by the counterweight 2. . The vertical movement of the car 1 is guided by the rail 5.
[0003]
As a method of routing the rope 3 in such an elevator, there is a method schematically shown in FIGS. 19 and 20, respectively. The method shown in FIG. 19 is a 1: 1 roping method in which the rope 3 is directly fixed to the car 1 and the counterweight 2. In the illustrated example, an intermediate pulley 6 is provided on the side of the counterweight 2. On the other hand, in the method of FIG. 20, the car 1 is provided with a car lower pulley 7 and the counterweight 2 is provided with a counterweight pulley 8 and an intermediate pulley 6, respectively. It is a 2: 1 roping method that is fixed to the building. This 2: 1 roping method can make the machine room and the car 1 in which the hoisting machine 4 and the like are installed relatively small. Therefore, when emphasis is placed on saving space in an elevator, a 2: 1 roping method is often used. When the 2: 1 roping method is adopted, it is necessary to provide the car 1 with a pulley. The pulley provided on the car may be provided at the lower part of the car 1 (FIG. 21) or may be provided at the upper part of the car 1 (FIG. 22). The former is called a lifting type, and the latter is a fishing type. Called.
[0004]
As a specific structure of the car 1 in the lift-type elevator, for example, a structure as disclosed in Patent Document 1 is known as a conventional general structure. 23 and 24 show examples. The car 1 includes a car room 9 and a car frame 10 that supports the car room 9. The car room 9 is formed in a square box shape, and has a flat car floor 11 at a lower portion. On the other hand, the car frame 10 includes a car frame base 12, a vertical frame (sling) 13, which is connected to a side end of the car frame base 12 and is provided in two right and left directions along the side surface of the car room 9. The frame 13 is connected at the upper part of the cab 9 to support the warp of the car frame 10 in the left-right direction, the front pillar 15 for attaching a car door (not shown), and the standing frame 13 and the front pillar at the upper part of the cab 9. 15 to support the distortion of the car frame 10 in the front-rear direction, the lower pulley support base 17 for attaching the two lower car pulleys 7 to the car frame base 12, and the depth of the car 1 (front-rear direction). The main component is a tie rod 18 attached to suppress the deformation of the car frame base 12 in the front-rear direction when the distance is large. A guide device 19 for receiving a guide by the rail 5 is attached to the vertical frame 13 above and below the car frame 10, and an emergency stop device 20 for an emergency stop operation when the rope 3 is broken is attached. ing. The car frame base 12 of the car frame 10 supports the car floor 11 of the car room 9 with the intervention of the vibration isolating rubber 21 to prevent the vibration from the car pulley 7 or the like from being transmitted to the room 9. The vibration is interrupted by the rubber 21.
[0005]
FIGS. 25 and 26 schematically show a conventional general structure example of the car frame base 12. The car frame base 12 includes a plurality of beam members as strength members, specifically, a pair of left and right vertical beam members 22a and 22b forming left and right sides, a pair of front and rear cross beam members 23a forming front and rear sides, 23b, a pair of intermediate cross members 24a, 24b provided in parallel with the cross members 23a, 23b form a rectangular frame structure as a whole. The support members 17a and 17b of the lower car pulley support 17 are fixed to the lower surfaces of the intermediate horizontal beam members 24a and 24b via the support members 25, respectively. 7a, 7b) are attached.
[0006]
In the lift type elevator, the rope 3 needs to pass outside the left and right ends of the car frame base 12. For this purpose, the lower cage pulleys 7a, 7b must be adapted to project their respective ends outside the longitudinal beam members 22a, 22b. Along with this, the lower cage pulleys 7a, 7b are made to protrude entirely below the car frame base 12 so that the lower cage pulleys 7a, 7b and the vertical beam members 22a, 22b do not interfere with each other. Will be attached. The anti-vibration rubbers 21 interposed between the car frame base 12 and the car floor 11 (FIGS. 23 and 24) of the car room 9 are arranged at the four corners of the car frame base 12 as seen in FIG. If necessary, they are generally arranged in the middle of these four corners. That is, the car room 9 is supported by the car frame base 12 via four to six support points by the vibration isolating rubber 21. In order to receive the point-like support by the vibration isolating rubber 21 as described above, it is necessary to give the car floor 11 of the cab 9 a large rigidity.

[Problems to be solved by the invention]
By the way, as for the elevator, it is desired to reduce the size of the car, particularly the size in the vertical direction, as much as possible. For example, in an elevator facility, a pit for installing a shock absorber or the like is provided below the hoistway, and the volume required for the pit also depends on the size of the car. The pit volume affects the utilization efficiency of the building in which the elevator equipment is provided. That is, in order to reduce the pit volume as much as possible and to increase the utilization efficiency of the building, it is necessary to reduce the size of the car in the vertical direction as much as possible.
[0009]
As described above, the elevator car is composed of the car room and the car frame supporting the car room, and the size in the vertical direction is determined by the size in the vertical direction of the car frame. Therefore, in order to reduce the vertical size of the car under the condition that the required size is given to the car room, it is required to reduce the vertical size of the car frame. Regarding the reduction in the vertical size of the car frame, in the case of a lift-type elevator, it is particularly effective to make the degree of protrusion of the car lower pulley projecting below the car frame base as small as possible. Changing the position of the vibration isolating rubber interposed between the car room and the car frame is also effective in reducing the vertical size of the car frame.
[0010]
The present invention has been made based on such knowledge, and it is possible to reduce the size of the car frame in the vertical direction by suppressing the degree of protrusion of the car lower pulley projecting below the car frame base for the lift type elevator. It is intended to be.
[0011]
Means for Solving the Invention
In order to achieve the above object, according to the present invention, a car frame and a car frame supporting the car room are provided, and the car frame supports the car room from below, and a car frame base, and a side end of the car frame base. And at least a vertical frame provided along the side of the cab and connected to the elevator car, wherein the elevator car has a lower car pulley attached to the lower car frame base. At least two of the plurality of beam members to be configured are used as pulley support / beam members, and mounting the under-car pulley to the car frame base directly fixes a bearing of the under-car pulley to the pulley support / beam member. Thereby, the lower car pulley is sandwiched between the pulley supporting and beam member.
[0012]
Further, in the present invention, for the lift type elevator as described above, the pulley-supporting / beam member is arranged along a diagonal line of the car floor of the cab, or the pulley-supporting / beam member is provided in the cab of the cab. It is arranged so as to be parallel to the side of the floor.

Further, in the present invention, in the lift-type elevator as described above, a guide device for guiding the vertical movement of the car is mounted on the stand frame with the interposition of a vibration isolating rubber.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. 1 to 4 schematically show the structure of a car in a lift-type elevator according to the first embodiment. In the present invention, a part of the beam member, which is a main strength member of the car frame base, is used as a pulley supporting / combined beam member, and the pulley supporting / combined beam member is supported so that the pulley under the car is sandwiched between the cage member and the car. The extent to which the pulleys protrude below the car frame base is suppressed, so that the size of the car frame in the vertical direction can be reduced. At least two types of this are possible, one is a type in which the pulley support / beam member is arranged along the diagonal line of the cab floor, and the other is a pulley support / beam member in the cab. This type is arranged parallel to the side of the floor. The first embodiment is an example of a type in which a pulley support / beam member is arranged diagonally. Hereinafter, the configuration will be specifically described.
[0016]
The car 100 in the present embodiment includes a car room 9 similar to the related art and a car frame 101 having a structure unique to the present invention. The car room 9 is formed in the shape of a square box as in the prior art, and has a flat car floor 11 at the lower part. The car frame 101 comprises a car frame base 102, a vertical frame 103 connected to the corners of the car frame base 102, and two right and left vertical frames 103 and left and right vertical frames 103 provided along the side surface of the cage 9. The main component is a crosshead 104 that supports the distortion of the car frame 101 in the left-right direction by connecting it at the upper part of 9, and some other components are added as necessary, but they are not shown. are doing. Note that the arrow in FIG. 1 indicates that the direction is in front of the car 100.
[0017]
The car frame base 102 is formed in a rectangular frame structure as a whole by a pulley supporting / supporting beam member 110, a cross diagonal beam member 111, an auxiliary horizontal beam member 112, and an auxiliary vertical beam member 113. The pulley supporting / supporting beam member 110 is formed using a channel-type mold steel to have a length substantially equal to the diagonal line of the car floor 11, and in addition to the function as a strength member for supporting the structural strength of the car frame base 102, the pulley under the car It also has a function to support the 7. The pulley supporting and serving beam members 110 are provided in parallel and side by side in a pair, and are provided at an interval suitable for supporting the pulley 7 under the car so as to sandwich the pulley 7 therebetween, and along the diagonal line of the car floor 11. Are arranged as follows. The support of the lower cage pulley 7 by the two pulley support / girder members 110, 110 is also performed by pulling the bearing 7B of the lower cage pulley 7 (a total of four on each of the left and right pulleys 7). By directly fixing to the lower surface of the beam member 110 with the intervention of the vibration isolating rubber 114, the upper side of the lower cage pulley 7 is sandwiched between the two pulley supporting and serving beam members 110, 110. Accordingly, the lower car pulley 7 is arranged on a diagonal line of the car frame base 102, that is, on a diagonal line of the car floor 11.
[0018]
The cross diagonally arranged beam member 111 is formed using I-shaped steel, and has a function as a strength member for supporting the structural strength of the car frame base 102 together with the pulley supporting and beam member 110, and a diagonally arranged pulley supporting and beam member. A pair of two wires 110 and 110 having their respective ends crossing each other are arranged vertically. The intersection of the cross diagonal beam member 111 and the pulley support / beam member 110 is reinforced by fastening with an L-shaped fastener 115 (FIG. 3) and by attaching a reinforcing plate 116 vertically. Both the auxiliary horizontal beam member 112 and the auxiliary vertical beam member 113 are connected to the end of the pulley supporting / shared beam member 110 and the end of the cross diagonally arranged beam member 111 along the side of the car floor 11 to thereby make the car frame. It has a function of reinforcing the structural strength of the base 102, and is formed using the same channel-type mold steel as the pulley support / beam member 110.
[0019]
The upright frame 103 is formed so as to have a groove structure by combining a pair of upright frame members 103p having an L-shaped cross section like an angle material. The stand frame 103 has its lower end fixed to the end of the cross diagonal beam member 111, that is, the corner of the car frame base 102, while its upper end is fixed to the crosshead 104. Further, a guide device 19 for receiving the guide by the above-described rail is fixed to each of the upper and lower ends of the stand frame 103 so as to fit in the groove. In order to fix the guide device 19, an anti-vibration rubber 117 is interposed as shown in FIG.
[0020]
In the first embodiment as described above, the lower car pulley 7 is supported so that the upper side is sandwiched between the two pulley support / beam members 110. For this reason, the upper part of the lower car pulley 7 enters the car frame base 102, and the degree of protrusion of the lower car pulley 7 to the lower side of the car frame base 102 can be reduced accordingly. The vertical size of the car frame 101 can be reduced for each minute. In the present embodiment, the car frame base 102 is formed in a so-called X-type structure by providing the pulley support / beam member 110 in a diagonal arrangement and providing a cross diagonal arrangement beam member 111 intersecting the diagonal arrangement. . Therefore, the rigidity of the car frame base 102 can be increased, and the height (thickness) of the car frame base 102 can be reduced accordingly. This also helps to reduce the vertical size of the car frame 101. Further, in the X-type structure including the pulley supporting / shared beam member 110 and the cross diagonal arrangement beam member 111, the lower car pulley 7 can be arranged on a diagonal line of the car floor 11. By fixing the stand frame 103 to the corner of the car frame base 102 under this arrangement, it becomes easy to position the center of gravity of the car 100 at the geometric center of the car 100. As a result, it becomes easier to obtain a car structure that is more resistant to shaking and falling. Further, in the present embodiment, the vibration transmitted through the car lower pulley 7 is blocked by the vibration-proof rubber 114, and the vibration transmitted through the guide device 19 is blocked by the vibration-proof rubber 117. For this reason, it is not necessary to interpose an anti-vibration rubber between the car frame base 102 and the car room 9. Therefore, the car room 9 can be supported by the entire car frame base 102. As a result, the rigidity required for the car floor 11 of the car room 9 can be reduced as compared with the conventional point-like support using the vibration-proof rubber. This also helps to reduce the vertical size of the car frame 101 because the car floor 11 can be made thinner. Further, in the present embodiment, since the upright frame 13 is arranged on the corner of the car frame base 102, that is, on the diagonal line of the car floor 11, the car door is attached to any of the four sides of the car 100. Can be placed.
[0021]
5 and 6 show a simplified structure of a car in a lift-type elevator according to the second embodiment. This embodiment is an example in which the first embodiment is slightly modified. The difference from the first embodiment is that the vibration isolating rubber 118 is interposed between the car frame base 102 and the car floor 11, while the vibration isolating rubber 114 (FIGS. 1 and 2) according to the first embodiment is different from the first embodiment. That is, the vibration rubber 117 (FIG. 4) is omitted. In such a structure, it is necessary to increase the rigidity of the car floor 11 by making the car floor 11 thicker than in the case of the structure in the first embodiment. This is a factor that increases the size of the car 100 in the vertical direction. However, on the other hand, the anti-vibration rubber 114 in the first embodiment can be omitted, so that the degree of protrusion of the lower car pulley 7 from the car frame base 102 is reduced. That is, the vertical size of the car 100 can be reduced. Other configurations and effects are the same as those of the first embodiment, and therefore, the same components are denoted by the same reference numerals in the drawings, and description thereof will be omitted.
[0022]
FIG. 7 shows a simplified structure of a car in a lift-type elevator according to the third embodiment. This embodiment is an example in which the first embodiment is slightly modified. In the present embodiment, the car frame base 102a is formed by a pulley support / beam member 110, a cross diagonal beam member 111, and an auxiliary cross beam member 112. That is, the second embodiment is different from the first embodiment in that the auxiliary vertical beam member 113 in the first embodiment is omitted. Such a structure may be adopted as long as the required strength can be given to the car frame base 102a. Other configurations and effects are the same as those of the first embodiment, and therefore, the same components are denoted by the same reference numerals in the drawings, and description thereof will be omitted.
[0023]
8 and 9 show a simplified structure of a car in a lift-type elevator according to the fourth embodiment. This embodiment is an example in which the first embodiment is slightly modified, and differs from the first embodiment in the direction of the upright frame 103. Specifically, in the case of the first embodiment, the upright frame 103 fixed to the end of the cross diagonal arrangement beam member 111 is arranged so that its groove portion faces the diagonal direction of the car frame base 102. (FIG. 1). On the other hand, in the present embodiment, the upright frame 103 fixed to the end of the cross diagonal arrangement beam member 111 is arranged so that the groove portion 103g (FIG. 9) faces the side surface of the car frame base 102.
[0024]
FIG. 10 schematically shows a planar arrangement relationship of the guide device 19, the car 100, the rail 5, the car pulley 7, and the rope 3. As shown in FIG. (A) shows the case of the car structure according to the first embodiment, and (B) shows the case of the car structure according to the present embodiment. In (A), the core of the rail 5 is located on a straight line connecting the guide devices 19 on both sides. On the other hand, in (B), the core of the rail 5 is not located on a straight line connecting the guide devices 19 on both sides. By the way, when a passenger rides in the car cabin unevenly, the car 100 tends to tilt due to the unbalanced load. The movement of the car 100 to be tilted is supported by the rail 5, but at this time, a load is applied to the guide device 19 to prevent the tilt. With respect to the inclination preventing load applied to the guide device 19, the arrangement structure of (A) is advantageous because it can be smaller than the arrangement structure of (B). On the other hand, with regard to fixing the rail 5 to the hoistway of the elevator, the arrangement structure of (B) is more advantageous than the arrangement structure of (A). That is, in the arrangement structure of (B), the bottom surface of the rail 5 is parallel to the side surface of the hoistway, so that the rail 5 is easily fixed. In the arrangement structure of (A), the bottom surface of the rail 5 is formed by the side surface of the hoistway. Therefore, the structure for fixing the rail 5 is complicated.
[0025]
The arrangement structure of the standing frame 103 according to the present embodiment and that according to the first embodiment have the above advantages and disadvantages. Therefore, both structures are appropriately selected in consideration of these. Other configurations and effects are the same as those of the first embodiment, and therefore, the same components are denoted by the same reference numerals in the drawings, and description thereof will be omitted.
[0026]
FIGS. 11 and 12 show a simplified structure of a car in a lift-type elevator according to the fifth embodiment. This embodiment is an example in which the fourth embodiment is slightly modified. In the present embodiment, the relationship between the pulley supporting and serving beam member 110 and the cross diagonally arranged beam member 111 in the car frame base 102b is different from that in the fourth embodiment. That is, the car frame base 102 according to the fourth embodiment is the same as the car frame base 102 according to the first embodiment, and the cross diagonal arrangement beam member 111 formed using I-shaped steel is divided into two. A pair of the two members was vertically arranged such that the respective ends of the pair of beam members 110, 110 cross each other. On the other hand, in the present embodiment, the cross diagonal beam member 111 is a single beam that passes through the diagonal of the car frame base 102. On the other hand, the pulley supporting / supporting beam member 110 is made shorter than half the diagonal length of the car floor 11, and the shortened pulley supporting / supporting beam member 110 is sandwiched on both sides of the cross diagonal arrangement beam member 111 with the lower cage pulley 7. The two are provided side by side at an interval suitable for supporting the main body. The two pulley supporting and serving beam members 110 provided on both sides of the crossed diagonally arranged beam member 111 are arranged so that each end thereof crosses the crossed diagonally arranged beam member 111 passing therethrough. At this intersection, as shown in FIG. 12, the pulley support / beam member 110 and the cross diagonally arranged beam member 111 are fastened by an L-shaped fastening member 115 and further reinforced by a reinforcing member 119.
[0027]
This embodiment is also different from the fourth embodiment in that the auxiliary longitudinal beam member 113 in the fourth embodiment is omitted. This is the same as the relationship of the third embodiment to the first embodiment, and such a structure may be used as long as the required strength can be given to the car frame base 102b. Other configurations and effects are the same as those of the fourth embodiment. Therefore, common components are denoted by the same reference numerals in the drawings, and description thereof will be omitted.
[0028]
13 to 15 schematically show the structure of a car in a lift-type elevator according to the sixth embodiment. The present embodiment is an example of a type in which a pulley support / beam member is arranged in parallel to a side of a floor of a cab. Hereinafter, the configuration will be specifically described. In addition, although this embodiment has a configuration common to each of the above-described embodiments, the same reference numerals are given in the drawings, and the description thereof is omitted as appropriate.
[0029]
The car frame 201 of the car 200 in the present embodiment has a car frame base 202. The car frame base 202 is a pulley supporting / using beam in which a channel type steel is used for an underframe 212 formed by combining two vertical beam members 210 and four horizontal beam members 211 each using an I-beam. It has a structure in which members 213 are combined. The underframe 212 is formed in a rectangular shape whose horizontal size is smaller than the horizontal size of the car 200 and whose vertical size is almost the same as the vertical size of the car 200. That is, the vertical beam member 210 is formed to have substantially the same length as the side of the car floor 11, and the horizontal beam member 211 is formed to be shorter than the side of the car floor 11. The underframe 212 is arranged so that the vertical beam member 210 and the horizontal beam member 211 are parallel to the side of the car 200.
[0030]
Two pulley support / beam members 213 are provided on the left and right sides of the underframe 212 at a suitable interval for supporting the lower car pulley 7 so as to sandwich the pulley 7, and a total of four pulleys are provided. The end is arranged to be perpendicular to the vertical beam member 210 of the underframe 212. That is, the pulley support / beam member 213 is arranged so as to be in parallel with the lateral side of the car floor 11. This pulley support / beam member 213 also has a function of supporting the pulley 7 under the car in addition to a function as a strength member for supporting the structural strength of the car frame base 202, as in the above embodiments. . The support of the lower cage pulley 7 by the pulley supporting / combining beam member 213 is parallel-arranged by directly fixing the bearings 7B of the car lower pulley 7 to the lower surface of the pulley supporting / combining beam member 213 with the interposition of the anti-vibration rubber 114. The two pulley support / beam members 213 sandwich the upper side of the car lower pulley 7. Therefore, the car lower pulleys 7 are arranged on the left and right sides of the car 200 so as to be arranged in parallel with the lateral sides of the car 200.
[0031]
As described above, since the pulley support / beam member 213 is arranged in parallel with the lateral side of the car floor 11, in the present embodiment, the pulley support / beam member 213 arranged in parallel with the car floor lateral side is arranged. The standing frame 103 is fixed to the car frame base 202. In order to fix the upright frame 103 to the car frame base 202 via the pulley support / beam member 213, it is necessary to arrange the upright frame 103 so that the upright frame 103 does not interfere with the car lower pulley 7. In order to avoid interference of the upright frame 103 with the lower car pulley 7, the upright frame 103 is displaced forward or rearward with respect to the lower car pulley 7. In the present embodiment, the stand frame 103 is disposed on the front side of the car lower pulley 7. For this purpose, the upright frame 103 is fixed to the car frame base 202 via a pulley support / beam member 213 located on the front side of the car lower pulley 7. Specifically, as shown in an enlarged view in FIG. 15, the lower end of the pair of upright frame members 103p, 103p forming the upright frame 103 has a lower end portion connected to a pulley supporting beam. An auxiliary horizontal beam member 214 is provided along the pulley support / beam member 213 for the front frame member 103p, and the lower end portion is fixed to the auxiliary horizontal beam member 214. It is to be noted that the guide device 19 is fixed to each of the upper and lower ends of the stand frame 103, and the anti-vibration rubber 117 is interposed for fixing the same as in the first embodiment.
[0032]
In the sixth embodiment as described above, the lower cage pulley 7 is supported so that the upper side is sandwiched between the two pulley support / beam members 213. As in the first embodiment, The vertical size of the car frame 201 can be reduced. Further, in the present embodiment, the vibration transmitted through the car lower pulley 7 is blocked by the vibration isolating rubber 114, and the vibration transmitted through the guide device 19 is blocked by the vibration isolating rubber 117. The same advantages as described with respect to the embodiment are obtained. Further, in the present embodiment, the pulley supporting / beam member 213 is arranged so as to be parallel to the lateral side of the car floor 11, and the stand frame 103 is fixed to the car frame base 202 via the pulley supporting / beam member 213. Like that. Therefore, the stand frame 103 is located along the side surface of the car 200. This arrangement is similar to that of a conventional elevator as described above with reference to FIGS. 23 and 24, and has the advantage that it is easier to fix the rail described with respect to the fourth embodiment. However, on the other hand, in a structure in which the pulley supporting / beam member 213 is arranged in parallel on the lateral side of the car floor 11, the vertical beam member 210 is prevented from interfering with the car lower pulley 7 supported by the pulley supporting / beam member 213. In order to do so, it is necessary to arrange the vertical beam member 210 in a structure like the underframe 212 so as to be offset inward from the vertical side of the car frame base 202. As a result, the support of the car room 9 by the car frame base 202 becomes uneven compared to the case of the first embodiment, and it may be necessary to increase the synthesis of the car floor 11 by that much.
[0033]
16 and 17 show a simplified structure of a car in a lift-type elevator according to the seventh embodiment. This embodiment is an example in which the sixth embodiment is slightly modified. The difference from the sixth embodiment is that while the vibration isolating rubber 118 is interposed between the car frame base 202 and the car floor 11, the vibration isolating rubber 114 (FIG. 14) and the vibration isolating rubber 117 according to the sixth embodiment are used. (FIG. 15) is omitted. This is the same as the difference between the first embodiment and the second embodiment. Other configurations and effects are the same as those of the sixth embodiment. Therefore, common components are denoted by the same reference numerals in the drawings, and description thereof is omitted.

【The invention's effect】
As described above, in the present invention, a part of the beam member, which is the strength member of the car frame base, is used as a pulley support / beam member, and the lower pulley is supported by the pulley support / beam member so as to sandwich the upper side. Thus, the upper part of the lower car pulley enters the car frame base. As a result, it is possible to reduce the extent to which the lower car pulley projects below the car frame base, and to reduce the vertical size of the car frame accordingly.
